Abstract (en)
[origin: EP0629679A2] A cyclone roof (12) has an aperture (10) and an outlet tube (22) extends through the aperture. A ring plate member (16) overlies the roof and its opening has a diameter smaller than the diameter of the roof aperture. The opening has an erosion protective covering (18) and defines a ware-resistant annular vent orifice (24) between the protective covering (18) and the outlet tube (22). <IMAGE>
